Doesn’t open properly. Try to re post.

Timing corrections to high. Try better fuel. What fuel were you using for this run?

 

[Cfarris87]

91 on this one. In CO, so don't have 93 here. I only hit the top tier stations here though

 

[ChaneRZ]

Regapped your plugs? Reset the ecu by disconnecting the - battery terminal for 5 minutes. If still you have corrections, well 91 sucks anyway.

 

[Cfarris87]

I haven't, I got my jb4 and plugs from a user here. They were gapped to recommended, but I don't recall the exact number. God I don't wanna take those out again lol ill try resetting the ecu. Mine Breitling explaining what I'm looking for on the log?

 

[Terry@BMS]

That's 91 octane life for you. Mixing in some E85 on race days will dramatically improve power over 91 octane alone, on all JB4 maps.

So found an e-85 station today, only had a few gallons left in the tank so I added 3.5 gal of e-85 and the rest 91 and made a few more pulls for logs. Not sure why it lumped all of them into one log. 1 pull in map 1 and 2 in map 2. Timings look to be a little higher? What numbers should I be looking to stay under on the ignition timing? And should I start troubleshooting with the plugs?

 

[cncBilly]

Not good. Try to reset your ECU by disconnecting negative battery terminal for 5 minutes. This will help it adjust to the new fuel. Then try try again. Cheers.

Logged again today after resetting the ecu. As you'll notice, I let up pretty quick after I saw some pretty high ign numbers. It looks like this log is strictly ign 1? Ign 2-6 sit suspiciously at 0.8

 

[ChaneRZ]

Ignore ign1. 0.8 is much better. That is with E85 mix right?

 

[Cfarris87]

Yeah, that's right. So I should only be looking at 2-6 for retards or advances? May try to get a map 2 log on the way home. Everything looks safe though, yeah?

 

[ChaneRZ]

Yes go with map2

Much better. So did you reset the ECU?

 

[Cfarris87]

Yeah, seemed to do the trick. Here's a few map 2 pulls from last night.

Bob’s your uncle! Looks like you can give map3 a try.

Ohhh boy
